Description

Technical Field

[0001] This utility model relates to the field of commutator material technology, specifically to a strip and a commutator. Background Technology

[0002] Commutator segments, also known as commutator segments of a commutator or brush commutator segments, are important components in equipment such as motors and generators, and are mainly used for switching current.

[0003] The main function of a commutator is to switch the direction of current in a motor or generator to ensure the correct direction of motor rotation. Especially in DC motors, the commutator switches the direction of current flow in real time by contacting the brushes. Therefore, the stable operation of the commutator is particularly important for the normal operation of the motor or generator.

[0004] In the prior art, commutator segments are usually made of copper or alloys because these materials have excellent conductivity and mechanical strength and can withstand high current and friction. However, in environments that require extremely low contact resistance, high wear resistance and corrosion resistance, commutator segments made of copper or alloys have the disadvantages of low wear resistance and low corrosion resistance, which affects the service life of the commutator segments and increases the cost of use. Therefore, this application is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a strip and commutator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a strip material, including a winding frame, wherein a strip material body for making commutator segments is wound on the outer wall of the winding frame, the strip material body includes copper sheets and two types of lifting components for improving the performance of the copper sheets, wherein one of the lifting components includes transverse grooves formed at the top and bottom of the outer wall of the strip material body, and a transverse plate is installed in the transverse groove, the transverse plate being made of precious metal.

[0007] Furthermore, the inner wall of the transverse groove is provided with several protrusions, and the outer wall of the transverse plate is provided with several protrusions that are adapted to the protrusions. The protrusions are inserted into the protrusions by installing the transverse plate in the transverse groove.

[0008] Furthermore, L-shaped grooves are provided on the top and bottom outer walls of the horizontal plate, and sturdy grooves adapted to the L-shaped grooves are provided on the top and bottom inner walls of the horizontal grooves. The L-shaped grooves and sturdy grooves are connected by the horizontal plate being installed in the horizontal grooves.

[0009] Furthermore, the protrusions are made of copper, and the L-shaped groove and the fixed groove are filled with liquid copper, and the connection between the horizontal plate and the horizontal groove is completed by the solidification of the liquid copper.

[0010] Furthermore, another type of lifting component includes a plurality of dotted grooves formed on the outer wall of the copper sheet, wherein protrusions are installed in the dotted grooves and the protrusions are made of precious metal.

[0011] A commutator segment is made by stamping the aforementioned strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The strip and commutator segments, through the set lifting components, allow precious metals to be embedded and installed on copper sheets. By combining the precious metals with the copper sheets to form the strip body, the wear resistance and corrosion resistance of the strip body can be improved, thereby extending the service life of the strip body and, consequently, the service life of the commutator segments. The type of precious metal can be selected according to actual usage requirements, and two different shapes of embedded lifting components are provided, allowing users to select the appropriate lifting components based on their own needs and costs, ensuring the stable operation of the commutator segments.

[0014] Meanwhile, by using grooves and protrusions, the contact area between the cross plate and the copper sheet can be increased, ensuring good contact between the strip body and the cross plate. The combination of groove and protrusion design helps to reduce contact resistance, improve conductivity, and thus improve the stability of the strip body. By using copper for the protrusions and filling the L-shaped grooves and the solid grooves with liquid copper, the connection between copper and precious metals can be established in advance, which also helps to make the cross plate more stable. By using the protrusions, the performance of the strip body can be locally improved according to the usage requirements, thereby locally improving the performance of the commutator segment. Compared with another type of lifting component, this lifting component is cheaper and easier for staff to select and use according to actual usage requirements. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Commutators are often used in the production of generators or engines to switch the direction of current. Commutator segments are an indispensable part of commutators. By using copper and precious metals as the strip material to make commutator segments, the service life of commutator segments can be extended and the stability of commutator segments can be improved.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a strip material, including a winding frame 1, on the outer wall of the winding frame 1 is a strip material body 2 for making commutator segments, the strip material body 2 includes a copper sheet 201 and two kinds of lifting components for improving the performance of the strip material body 2, one of the lifting components includes a transverse groove 202 opened at the top and bottom of the outer wall of the strip material body 2, a transverse plate 204 installed in the transverse groove 202, the transverse plate 204 being made of precious metal.

[0024] It is important to note that by using copper sheet 201 as the substrate of strip body 2 to ensure good conductivity, the performance of strip body 2 can be improved by setting up lifting components, so as to extend the service life of strip body 2. Two lifting components are provided, which can be selected by the staff according to the actual use needs. By using one of the lifting components, through the cross groove 202 and the cross plate 204, and the cross plate 204 is made of precious metal, the conductivity and strength of strip body 2 can be improved. This can significantly improve the conductivity and mechanical strength of commutator segments made from strip body 2, while also helping to reduce wear and arcing, extend the service life of commutator segments, improve stability, and reduce usage costs.

[0025] like Figure 2 and Figure 3 As shown, the inner wall of the transverse groove 202 is provided with several protrusions 203, and the outer wall of the transverse plate 204 is provided with several protrusions 205 that are adapted to the protrusions 203. The protrusions 205 are inserted into the protrusions 203 by the transverse plate 204 being installed in the transverse groove 202.

[0026] It should be noted that by using the groove 203 in conjunction with the protrusion 205, the contact area between the horizontal plate 204 and the copper sheet 201 can be increased, ensuring good contact between the strip body 2 and the horizontal plate 204. The design of the groove 203 and the protrusion 205 helps to reduce contact resistance, improve conductivity, and thus improve the stability of the strip body 2.

[0027] like Figure 4 As shown, L-shaped grooves 207 are provided on the top and bottom outer walls of the horizontal plate 204, and fixed grooves 206 adapted to the L-shaped grooves 207 are provided on the top and bottom inner walls of the horizontal groove 202. The L-shaped grooves 207 and fixed grooves 206 are connected by the horizontal plate 204 being installed in the horizontal groove 202.

[0028] It should be noted that by using the L-shaped groove 207 in conjunction with the retaining groove 206, it is easy to fill the adhesive, making the installation of the horizontal plate 204 in the horizontal groove 202 more stable. By using the L-shaped groove 207 in conjunction with the retaining groove 206 and the convex groove 203 in conjunction with the convex point 205, the horizontal plate 204 is not easy to move in the horizontal groove 202, ensuring the stability of the commutator segment made of the strip body 2.

[0029] like Figure 2 and Figure 4 As shown, the protrusion 205 is made of copper, and the L-shaped groove 207 and the solid groove 206 are filled with liquid copper. The connection between the horizontal plate 204 and the horizontal groove 202 is completed by the solidification of the liquid copper.

[0030] It should be noted that by making the protrusions 205 copper and filling the L-shaped grooves 207 and the reinforcing grooves 206 with liquid copper, the connection between copper and precious metals can be established in advance, which also helps to make the horizontal plate 204 more stable.

[0031] like Figure 5 As shown, another lifting component includes several dot-shaped grooves formed on the outer wall of the copper sheet 201, and protrusions 208 are installed in the dot-shaped grooves. The protrusions 208 are made of precious metal.

[0032] It should be noted that by setting the protrusion 208, the performance of the strip body 2 can be locally improved according to the usage requirements, thereby locally improving the performance of the commutator segment. Compared with another type of improvement component, this improvement component has a lower cost and is easier for staff to select and use according to actual usage requirements. The commutator segment is made by stamping the strip body 2. In order to further improve the wear resistance of the strip body 2, a wear-resistant layer can also be filled on the strip body 2.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
